LOUISVILLE, Ky. (WDRB) -- Kentucky Kingdom's T3 roller coaster reopened Monday afternoon after a two-day closure to determine why train cars bumped into each other on Saturday.

State ride inspectors cleared the ride to open again, Kentucky Kingdom spokesperson Adam Birkner said in a news release.

Inspectors from the Kentucky Department of Agriculture will allow the ride "to function with one car instead of two," department spokesperson Sean Southard said in an email Monday afternoon.

A lightning strike during thunderstorms Thursday may have affected the coaster's electronic control system, Birkner said. 

"Because the coaster has many redundant safety systems, the braking system was still essentially intact. Therefore, there was only slight contact between the trains, causing some minor cosmetic damage," Birkner said.

The T3 suspended looping coaster closed around 2:30 p.m. Saturday after one of the train cars bumped into another train as it was waiting to enter the station for unloading, the park said.

The second train has been removed for "some paint touch-up" and will be checked by state inspectors before it operates again, the park said. 

The park notified state ride inspectors after the incident Saturday. Inspectors responded Saturday and remained at the park Sunday and Monday. The notification came within the 12-hour window allowed by state regulation, Southard said.

The ride passed its last state inspection on April 26, Southard said.

Five riders were taken to the park's health services center for evaluation after the incident, the park said. Four were released, and the fifth person was taken to a local hospital.
